Never had the pleasure of hearing the TSM or VSM, but have had the older model 2B, 3B+, and 4B. My son still runs 3B+ with his B&K amp.
There won't be any new ones....even if you move on to something else, I'd still hold on to them.
Are Merlin TSM speakers buried with their owners?
For now....I have decided to stick with my TSMs. I spent a LOT of time on the internet trying to find any discussion of speakers that people have moved on to from their Merlins. I can't find a darn thing. Someday, I'd like to move on just to try something different (the change disease is terrible with no cure). I'm sure there are probably speakers for $10k that I could buy, but I'm not looking to go that route. Very frustrating and quite perplexing.
